The men hit Marquis Jewelers on Broadway near Palomar Street about 5:30 p.m.

They broke a glass display case and took gold bracelets, rings and earrings, then left, Chula Vista police said.

A parking lot security camera showed that the men ran toward an apartment complex, then drove away in a large, dark sport utility vehicle. The robber with the gun is believed to be Latino and the other man, who wore a bandanna over his face, was black. No other descriptions were immediately available from police.
